Configuring VINES Services
1-16 117372-A Rev. A
Nodes that can route VINES packets and have a static, unique, 32-bit network
number implement these services; they are usually service nodes.
• Address resolution clients
Nodes that do not have a VINES address implement these clients; they are
usually client nodes.
VINES Sequenced Address Resolution Protocol
VINES Sequenced Address Resolution Protocol (Sequenced ARP) works with
Sequenced RTP. With VINES Sequenced ARP, a client receives an assignment
response that includes the VINES address, sequence number, and metric of the
routing server. The routers that receive the VINES 5.50 client Sequenced ARP
requests or assignment requests will respond automatically with Sequenced ARP
response packets.
You can disable or enable VINES ARP on a router, using the ARP Enable
parameter. Refer to Cha
pter 4 for details about this parameter.
VINES Internet Control Protocol
VINES Internet Control Protocol (ICP) supports certain transport layer protocol
entities by reporting network errors and topological conditions. A VINES ICP
packet has a 4-byte header and follows the VINES IP header (F
igure 1-8).
Figure 1-8. VINES Internet Control Protocol Header
The ICP entity generates these two types of ICP packets:
• Exception notification packets
Packet type (2 bytes)
Exception or metric (1 byte)
4 bytes
